The most obvious problem is that your sample is a run-on sentence. The text should be divided between "block" and "some"

"... around the block. Some people ..."

" ... around the block; some people ..."

" ... around the block, and some people ..."

Also, was there one line or multiple lines? It is more common to say "The line for ..." rather than "Lines for ..." And, although not wrong, various authorities consider "some people" to be wordy. You could use either "some" or "people" and convey the same meaning.
